Characterization Of Animal And Plant Proteins Glycated With Konjac Glucomannan Hydrolysate, Pachara Pomsang

Chulalongkorn University Theses and Dissertations (Chula ETD)

This study aimed to prepare Konjac glucomannan hydrolysate (KGMH) and investigate its glycation with animal and plant proteins through the Maillard reaction, focusing on varying degrees of polymerization (DPs). Initially, KGMH was produced from high-content Konjac glucomannan (KGM) using beta-mannanase (200 to 300 U/g) within 60 minutes, resulting in KGMH with DPs ranging from 2 to 9 and reduced viscosity. Under optimized conditions (40% KGM and 250 U/g enzyme), KGMH samples with the widest DP range (4.20 to 6.11) were used to assess antioxidant and antiglycation activities. Lower DPs of KGMH showed superior antioxidant activities in DPPH and ABTS assays …

Image-Base Adaptive Proportional Topology Optimization Of Infill Structure Using Polygon Sbfe Approach, Sompong Rungsawang

Chulalongkorn University Theses and Dissertations (Chula ETD)

The use of infill structures is widespread in additive manufacturing applications, offering porous domains that are well-suited for withstanding various physical loadings. This thesis introduces a novel approach, namely Proportional Topology Optimization (PTO), leveraging an automatic image-based quadtree Scaled Boundary Finite Element (SBFE) framework. The SBFE, where sub-domains are treated as polygonal elements in 2D, is employed to address the hanging node issue. The methodology is extended to design infill structures by minimizing compliance concerning force variations, subject to local volume fraction constraints rather than a global volume constraint for each element in the design domain. Material density for each …

Climate, Physiology, And Distributions: The Role Of Thermal Physiology In Biological Invasions, Sean D. Powers

Theses and Dissertations

Climate is a primary factor influencing species range dynamics, particularly for ectotherms whose body temperature is closely tied to the surrounding conditions. While range shifts of ectotherms are attributed to climate warming, the mechanism driving these shifts are not well understood. Studies in macrophysiology demonstrate that the interaction of climate with thermal physiology plays a key role in determining large-scale spatial and temporal patterns for many temperature-sensitive physiological traits. This work has revealed a clear relationship between thermal tolerance breadth and range size. However, more recent analyses of this relationship demonstrate that thermal tolerance breadth only provides a partial explanation …

Developing Ecologically Valid Clinical Tools For Persons With Tbi: Understanding The Role And Impact Of Distractions, Deanna Pinnow

Theses and Dissertations--Rehabilitation Sciences

There is a critical need for the development of ecologically valid clinical tools to assess real-life cognitive functioning in persons impacted by traumatic brain injury (TBI). Chronic cognitive impairments that are exacerbated by distractions are one of the core factors contributing to poor home and community re-integration post injury. Simulation-based digital platforms (i.e., virtual reality, augmented reality, and mixed reality) have become potential solutions for eliciting real-world cognitive performance in clinical settings. Yet, there is a paucity of research investigating the role and impact of distractions on cognition. As a result, there is no clear framework of measuring distractions to …

Redescription Of Adults And First Description Of The Larva Of Haemaphysalis (Rhipistoma) Adleri Feldman-Muhsam, 1951 (Acari: Ixodidae), Parasite Of Carnivorans In Western Asia, Cole Anderson

Honors College Theses

The adult ticks of Haemaphysalis (Rhipistoma) adleri Feldman-Muhsam, 1951 (Acari: Ixodidae) are redescribed and the larva of this species is described for the first time here. The adults of H. adleri that we studied were collected from various canid, felid and hyaenid carnivorans (Carnivora: Canidae, Felidae, Hyaenidae) as well as a hedgehog (Erinaceomorpha: Erinaceidae) in Iraq, Israel and West Bank. The males, females and larvae of H. adleri can be differentiated from Haemaphysalis (Rhipistoma) species occurring in the Palearctic portion of West Asia and Egypt as well those in the H. asiatica subgroup by the length of idiosomal …

Federal Rules Of Private Enforcement, Luke Norris, David L. Noll

Law Faculty Publications

The Federal Rules of Civil Procedure were made for a different world. Fast approaching their hundredth anniversary, the Rules reflect the state of litigation in the first few decades of the twentieth century and the then-prevailing distinction between "substantive" rights and the "procedure" used to adjudicate them. The role of procedure, the rulemakers believed, was to resolve private disputes fairly and efficiently. Today, a substantial portion of litigation in federal court is brought under regulatory statutes that deploy private lawsuits to enforce public regulatory policy. This type of litigation, which scholars refer to as "private enforcement," is the engine for …

Liaising The Catalog: Collaborating Across Library Departments To Promote Successful Discoverability Through Enhanced Cataloging, Tammie Busch, Debbie Campbell, Susan Howell, Mary Konkel, Dennis Krieb, Mingyan Li, Cathy Mayer, Ross Taft

SIUE Faculty Research, Scholarship, and Creative Activity

Academic libraries are increasingly asked to articulate connections between the work of library staff and student success. This article discusses how a team of librarians participating in CARLI Counts, an immersive professional development program funded by a Laura Bush 21st Century Librarian Grant through the Institute of Museum and Library Services, responded to the lack of research investigating the indirect impact of the work of technical services staff on student learning. An anonymous online survey distributed to library staff of the Consortium of Academic and Research Libraries in Illinois (CARLI) member institutions explored the perceived value of enhanced cataloging in …

An Integrated Conceptual Framework Linking Attachment Insecurity To Increased Risk For Both Enacting And Experiencing Objectification, Frances C. Calkins, Sarah Gervais, Gemma Sáez, Meredith J. Martin, M. Meghan Davidson, Rebecca L. Brock

Department of Psychology: Faculty Publications

Sexual objectification (i.e., reducing a person to their appearance, body, or sex appeal and functions) is a significant risk factor for negative health outcomes. In the present investigation, we examined multiple manifestations of objectification (i.e., objectification of others, objectification of self, and objectification by others) in an interpersonal context. We merged objectification theory with attachment theory, one of the most prominent theories of close relationships, and propose that sexual objectification can shed light on attachment processes (and vice versa). To bolster this conceptual overlap, we tested this novel, integrated framework across two independent samples of women and men including (a) …

Of Dogs And Bonds, Jeffrey R. Stevens

Department of Psychology: Faculty Publications

In four of Charles Darwin’s classic works (Darwin, 1859, 1868, 1871, 1872), the domestic dog (Canis familiaris or Canis lupus familiaris)¹ featured prominently, offering key examples to illustrate his ideas about evolution, domestication, comparative behavior and cognition, and emotional expression. Darwin held a clear fondness for dogs, and when replying to letters detailing the “sagacity” of dogs, he remarked “I can believe almost anything about them” (Darwin, 2014). Despite the early interest in their behavior and cognition by a number of leading scientists, dogs were rarely subject to serious investigation as a study species for 150 years. …

Place Conditioning In Humans: Opportunities For Translational Research, Seetha Krishnan, Rick A. Bevins, Harriet De Wit

Department of Psychology: Faculty Publications

Rationale Translational research, especially research that bridges studies with humans and nonhuman species, is critical to advancing our understanding of human disorders such as addiction. This advancement requires reliable and rigorous models to study the underlying constructs contributing to the maladaptive behavior.

Objective In this commentary, we address some of the challenges of conducting translational research by examining a single procedure, place conditioning. Place conditioning is commonly used with laboratory animals to study the conditioned rewarding effects of drugs, and recent studies indicate that a similar procedure can be used in humans.

Results We discuss the opportunities and challenges of …

Objectives: This study examined the effects of a combination corticosteroid plus long-acting beta2-adrenergic agonist inhaler (IC) on rabbit phonation. Methods: White New Zealand male rabbits were assigned randomly to experimental and control groups (n = 11 per group). The experimental group received twice-daily doses of Advair HFA™ (fluticasone propionate 45 mcg and salmeterol 21 mcg) via a veterinary facemask with 1-way valve and spacer; the control group received aerosolized saline. After 8 weeks, animals were euthanized, larynges excised, frozen, and subsequently thawed and mounted on a standard bench apparatus. Phonation was elicited during 15 successive trials, and phonation threshold pressure …

Data Visualization In 10-K Filings, Theodore E. Christensen, Karson E. Fronk, Joshua A. Lee, Karen K. Nelson

Faculty Publications

The Securities and Exchange Commission encourages the presentation of information or data in graphical form to improve users’ ability to understand financial disclosures. We find a dramatic increase in the disclosure of both qualitative and quantitative infographics in 10-K filings over time and substantial cross-sectional variation in firms’ choices regarding image types, data content, and the placement of infographics within 10-Ks. We provide evidence on factors associated with firms’ use of infographics and explore the persistence with which they are disclosed over time. Finally, we investigate the relation between the use of infographics and uncertainty in capital markets.

Potential Repercussions Of Offshore Wind Energy Development In The Northeast United States For The Atlantic Surfclam Survey And Population Assessment, Sarah Borsetti, Daphne M. Munroe, Andrew M. Scheld, Eric N. Powell, John M. Klinck, Eileen E. Hofmann

CCPO Publications

The Atlantic surfclam Spisula solidissima fishery, which spans the U.S. Northeast continental shelf, is among the most exposed to offshore wind energy development impacts because of the overlap of fishing grounds with wind energy lease areas, the hydraulic dredges used by the fishing vessels, and the location of vessel home ports relative to the fishing grounds. The Atlantic surfclam federal assessment survey is conducted using a commercial fishing vessel in locations that overlap with the offshore wind energy development. Once wind energy turbines, cables, and scour protection are installed, survey operations within wind energy lease areas may be curtailed or …

Examining The Connectivity Of Antarctic Krill On The West Antarctic Peninsula: Implications For Pygoscelis Penguin Biogeography And Population Dynamics, Katherine L. Gallagher, Michael S. Dinniman, Heather J. Lynch

CCPO Publications

Antarctic krill (Euphausia superba) are considered a keystone species for higher trophic level predators along the West Antarctic Peninsula (WAP) during the austral summer. The connectivity of these populations may play a critical role in predator biogeography, especially for central-place foragers such as the Pygoscelis penguins that breed along the WAP during the austral summer. Here, we used a physical ocean model to examine adult krill connectivity in this region using simulated krill with realistic diel vertical migration behaviors across four austral summers. Specifically, we examined krill connectivity around the Adélie gap, a 400 km long region along …

Interactive Effects Of Climate Change-Induced Range Shifts And Wind Energy Development On Future Economic Conditions Of The Atlantic Surfclam Fishery, Stephanie Stromp, Andrew M. Scheld, John M. Klinck, Daphne M. Munroe, Eric N. Powell, Roger Mann, Sarah Borsetti, Eileen E. Hofmann

CCPO Publications

Rising water temperatures along the northeastern U.S. continental shelf have resulted in an offshore range shift of the Atlantic surfclam Spisula solidissima to waters still occupied by ocean quahogs Arctica islandica. Fishers presently are prohibited from landing both Atlantic surfclams and ocean quahogs in the same catch, thus limiting fishing to locations where the target species can be sorted on deck. Wind energy development on and around the fishing grounds will further restrict the fishery. A spatially explicit model of the Atlantic surfclam fishery (Spatially Explicit Fishery Economics Simulator) has the ability to simulate the consequences of fishery displacement …

The Southern Ocean Ecosystem Affects The Entire World, Eugene J. Murphy, Nadine M. Johnston, Eileen E. Hofmann, Richard A. Phillips, Jennifer E. Jackson, Andrew J. Constable

CCPO Publications

The Southern Ocean, which flows around the Antarctic continent, is home to vast numbers of unique and remarkable animals, including penguins, albatrosses, petrels, seals, and whales. The ocean bursts into life every spring, fueling a summer feeding and breeding frenzy. During the dark winter months, there is little food and life is very harsh. Human activities such as fishing and pollution are affecting this ecosystem, as is climate change. These ecosystem changes matter beyond the Southern Ocean! Ocean currents carry nutrients and organisms into and out of the Southern Ocean. Many marine mammals and seabirds swim or fly in and …

Waste And Chemical Management In A 4°C World, Michael B. Gerrard

Faculty Scholarship

Many chemicals and hazardous substances are kept in places that can withstand ordinary rain, but not severe storms or floods. If these events occur and the chemicals are released, people and the environment may be endangered. This Article discusses the hazards posed to chemical and waste disposal facilities by extreme weather events that would be worsened as a result of climate change, and how U.S. laws do (or do not) deal with these hazards; and considers how the law would need to change to cope with what would happen to these facilities in a potentially 4°C world. It is adapted …

The Logic And Limits Of The Federal Reserve Act, Lev Menand

Faculty Scholarship

The Federal Reserve is a monetary authority subject to minimal executive and judicial oversight. It also has the power to create money, which permits it to disburse funds without drawing on the U.S. Treasury. Since 2008, it has leveraged this power to an unprecedented extent. It has rescued teetering financial conglomerates, purchased trillions of dollars of mortgage-backed securities, and opened numerous ad hoc lending facilities to support ordinary businesses, nonprofits, and municipalities.

This Article identifies the causes and consequences of the Federal Reserve's expanded footprint by recovering the logic and limits of its enabling act. It argues that to understand …

Walking The Line: The Politics Of Federalism And Environmental Change, Allan C. Hutchinson

Articles & Book Chapters

This short paper looks at the Greenhouse Gas Pollution Pricing Act decision through a wider and more critical jurisprudential lens. In so doing, I demonstrate that the courts are no less political than legislatures in making decisions about who has the constitutional capacity to decide on how the challenges of climate change should be met. This is not so much a criticism of the Supreme Court of Canada, but an inevitable feature of constitutional law. After introducing the traditional and received explanation of the differences between political decision-making and judicial decision-making, I delve deeper into the Court's opinions and show …

More Than The Sum Of Its Parts: Unlocking The Power Of Network Structure For Understanding Organization And Function In Microbiomes, J P. Dundore-Arias, M Michalska-Smith, M Millican, L L. Kinkel

Biology, Agriculture and Chemistry Faculty Publications and Presentations

Plant and soil microbiomes are integral to the health and productivity of plants and ecosystems, yet researchers struggle to identify microbiome characteristics important for providing beneficial outcomes. Network analysis offers a shift in analytical framework beyond "who is present" to the organization or patterns of coexistence between microbes within the microbiome. Because microbial phenotypes are often significantly impacted by coexisting populations, patterns of coexistence within microbiomes are likely to be especially important in predicting functional outcomes. Here, we provide an overview of the how and why of network analysis in microbiome research, highlighting the ways in which network analyses have …

The Future Concept Of Work, Nicola Countouris, Valerio De Stefano

Articles & Book Chapters

This chapter offers a reappraisal of the idea of ‘personal work’ and a critical assessment of the concept of subordination, which shapes the traditional contract of employment and subordinate work. The authors suggest that the notion of personal work may be more useful in attempts to develop a newly conceptualised concept of human labour, one capable of incorporating certain dimensions of (unpaid) gendered labour, ‘heteromated’ labour (‘heteromation’ is the extraction of economic value from low-cost or free labour in computer-mediated networks), and other forms of socially (and ecologically) valuable labour that hitherto have been excluded from the realm of formal, …

Workers' Boards: Sectoral Bargaining And Standard-Setting Mechanisms For The New Gilded Age, Sara Slinn

Articles & Book Chapters

This article explores the potential of sectoral standard-setting models (often referred to as “wage boards” or “workers’ boards”) as a solution for contemporary workplace issues, which existing labor relations and minimum standards regulatory systems continue to struggle to address. This argument, the article examines three historical statutory systems of sector-based minimum workplace standard-setting established in the early 20th century as a response to unacceptable wages and working conditions: the British Wages Council system, the Canadian Industrial Standards Act, and the US Fair Labor Standards Act. The article applies the conceptions of fairness identified in Seth Harris's study of the origins …

The Effect Of Testing On New Learning Of Related And Unrelated Text Sections, Katie Ingram

UNF Graduate Theses and Dissertations

When individuals are presented with a variety of materials, including word lists, face-name pairs, text passages, and more, the presence of a test between sections can enhance future section learning, a phenomenon called the forward testing effect (FTE). In addition to the FTE, studies have suggested that a decrease in the relatedness of the subject matter units can increase learning of the material. The current study examined the interaction between the presence of a test and the relatedness of material using text sections and cued-recall questions. Participants were 119 individuals assigned to a related test, related no-test, unrelated test, or …
